Complications

Heat-related illnesses are the most serious complications of anhidrosis. Children are especially vulnerable because their core temperatures rise faster than adults', and their bodies release heat less efficiently.

Heat-related problems include:

• Heat cramps. Symptoms include muscle pain or spasms. Rest in a cool place and drink water or a sports drink. Get medical help if cramps last longer than an hour.
• Heat exhaustion. Signs and symptoms include weakness, nausea and a rapid pulse. Move to a cool place and get medical help if symptoms last longer than an hour.
• Heatstroke. This life-threatening condition occurs when your body temperature reaches 103 F (39.5 C) or higher. Skin may be hot, red or dry. If not treated immediately, heatstroke can cause loss of consciousness.
